More human-friendly antibacterial coating made from gold

We've been hearing a lot about the antibacterial qualities of silver, with silver nanoparticles finding use in everything from water filters to food packaging. Unfortunately, there are also concerns about the toxicity of those particles, particularly when they enter our bodies. Now, however, Polish scientists have developed what they claim is a safer alternative – an antibacterial coating that kills microbes using gold. Read More

Oil-exuding silicone could prevent bacterial infections

Whenever foreign objects such as catheters, implants or other devices are placed within the human body, there's a danger that bacterial colonies known as biofilms could collect on them, leading to infections. Now, however, scientists at Harvard University's Wyss Institute have created a material that's too slippery for those biofilms to cling onto. It works by continuously releasing oil. Read More

Smart dust could put telescopes in a spray can

Good things come in small packages – and sometimes in aerosol cans. To prove this, researchers at the Rochester Institute of Technology (RIT) and NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California are working on technology for a future generation of space telescopes that may one day see the giant instruments replaced by swarms of particles that are deployed from a can and herded into place by laser beams.

New method of conserving wood gets tested on historic ship artifacts

In 1545 Henry VIII’s flagship the Mary Rose sank suddenly under mysterious circumstances. In 1982, the rediscovered ship was raised to the surface in a remarkable feat of underwater archaeology that sparked decades of heroic preservation work. Now a team of scientists led by the University of Cambridge is working with the Mary Rose Trust conservation team to test a new way of conserving waterlogged wood in order to preserve the great ship and her cargo of history for later generations.

Polyes Q1 aims to be the first child-safe 3D sketching pen

Startup company Future Make 3D is developing the Polyes Q1, a 3D pen with a slew of safety features that aims to make it fun and safe for everyone – children included – to sketch out three-dimensional sculptures made of plastic. The cordless, USB-charged pen will come with standard, glow-in-the-dark, transparent and temperature-changing inks and is set to hit Kickstarter sometime next month. Read More

MIT scientists use polymer scaffold to stimulate bone growth

A team of chemical engineers from MIT has developed a new method of stimulating bone growth, by utilizing the same chemical processes that occur naturally in the human body following an injury such as a broken or fractured bone. The technique involves the insertion of a porous scaffold coated with growth factors that prompt the body's own cells to naturally mend the damaged or deformed bone. Read More

Spongy polymer developed to fill holes in bones

Whether they're the result of injuries, surgery or birth defects such as cleft palate, missing sections of bone in the skull or jaw can certainly affect someone's appearance. Although there are some methods of filling in such gaps, they have limitations that limit their application. A newly-developed foam-like material, however, may be able to succeed where other approaches have failed. Read More

Polymer-based graphene substitute is easy to mass-produce

For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.
